7 Claims. ((31, 1

This invention relates to improvements in eye cups.

The main objects of this invention are:

First, to provide an eye cup adapted for use in combination with abottle or like container whereby a closure is providedfor the containerand the cup is adapted for immediate use merely by positioning andtilting the bottle so that the liquid therefrom will flow into the cup,means being provided for preventing the used liquid. from returning tothe container.

Second, to provide a structure having these advantages which is veryconvenient to use and easily kept in a sanitary condition;

Third, to provide an eye cup adapted as'a stopper which may be used onbottles or like containers to charge the cup merely by positioningthecup and inverting or tilting the container, and the contents of the cupmay be readily discharged and the cup repeatedly used for the fullcapacity of the container.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, in which: i

Fig. 1 is a vertical section on line II of Fig. 3

of my improved cup in combination with a glass bottle, a fragment onlyof the upper portion of the bottle being illustrated.

Fig. 2 is a side elevation of the cupremoved from the container.

Fig. 3 is a plan View. I

In the embodiment of my invention illustrated, l represents a bottleadapted to contain aneye wash or eye treating fluid having the usualneck 2. I have illustrated my invention as adapted to a bottle as eyewash preparations are commonly supplied in bottles or may be preparedand conveniently stored in bottles provided with the usual cork.

My improved eye cup 3 has a suitably conformed rim 4 having high and lowportions adapted for application as is customary with eye cups. This eyecup is provided. with a stem 5 constituting a stopper for the bottle orcontainer 2. This stem has a longitudinal passage 6 which is extendedinto branches or delivery passages l, the outer ends 8 of which areadjacent the top of high portions of the rim of the cup. These passageshave return directed delivery portions 9 which open at l0, into the eyecup at points substantially below low portions of the rim of the cup.

With the parts thus arranged, when the cup is assembled with thecontainer, as I, and applied to the eye and inverted, the fluid willflow into the cup, completely filling it. -A pluralityof passages arepreferably provided to insure more prompt filling of the cup although asingle passage is effective. The plurality of passages, how-.

ever, allows the rim of the cup being held in close sealing relation sothat air displaced by the incoming liquid through one delivery passagecscapes into the-container through the other.

When the eye treatment is completed, the eye cup and container is swungin upright position and the cup removed from the eye when the concup maybe readily wiped or cleaned.

.While I illustrate in the accompanying draw ing' a bottle as acontainer, it will be understood that special types of containers may beemployed if desired.

I have not illustrated other modifications or adaptations of myinvention which I contemplate as it is believed that this disclosurewill enable those skilled in the art to embody or adapt my invention asmay be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a bottle, of an eye cup having'a stemconstituting a stopper for the bottle and provided with a longitudinalpassage, the wall of the cup having delivery pa s sages thereincommunicating withsaid passage in said stem, the outer .ends of saiddelivery passages being adjacent the rimof the cup and having rearwardlydirected return portions opening into the cup at points substantiallyspace from the rim of the cup.

2. The combination with a bottle, of an eye cup having a' stemconstituting a stopper for the bottle, the cup having a delivery passagetherein opening at the inner end of the stem and extending to a pointadjacent the rim of the cup and having a return portion opening into thecup at apoint substantially spaced from the rim of the cup to provide afluid return trap.

3. The combination with a bottle, of an eye cup having a stemconstituting a stopper for the bottle, the cup having a delivery passagetherein opening at the inner end of the stem and having a returndirected discharge portion opening into the cup at a point spaced fromthe rim of the cup.
